The Electronics Information subtest of the ASVAB consists of 20 multiple choice questions, which must be answered in 9 minutes. Below are a few sample questions which are very similar to the actual questions you'll see on the ASVAB:
1. To convert DC to AC, which device is used?
2. Ohm’s law can be written in each of the following ways EXCEPT:
(A) R = V/I
(B) I = V/R
(C) V = IR
(D) V = I/R
3. Two electrical wires run to a machine. One wire is 6mm thick, and the other is 3mm thick. For the two wires to carry the same current, the larger wire
(A) requires less voltage.
(B) requires more voltage.
(C) requires the same voltage.
(D) It cannot be determined from the information given.
4. To measure the flow of current through a circuit, you would use a(n):
5. In a closed electrical circuit,
(A) one terminal is always positive, and one terminal is always negative.
(B) both terminals can be positive.
(C) both terminals can be negative.
(D) terminals are neither positive nor negative.
1. (A) 2. (D) 3. (A) 4. (B) 5. (A)
